Patent FR-2447813-A1 (FR)
Title: Multiple track printer mechanism - has partial measurement position selection with common input changeover switch and print wheel control
IPC: G01D9/32
Filed: 1980-01-30
Abstract: A multiple track printer has a mechanism for switching its measurement signal input between different measurement positions and a print wheel (9). It enables selection not only of single measurement positions but also of a partial value greater than one. The print wheel position motor (7) is controlled using a code common to the control of the input switch over device. This enables each output position to be directly attainable from each other output position. The motor contains an alternating excitation pole in a stator with auxiliary poles.

Patent FR-2449844-A1 (FR)
IPC: F21S6/00
Filed: 1980-02-14
Abstract: A spherical head contains a module consisting of a halogen incandescent lamp and reflector (18), and is mounted on a cubic support (2) having electrical operating devices (6, 9). The housing (1) of the luminair head has the function purely of screening the module, and is supported, in common with the holder (17) for the module as well as a diaphragm ring (19) framing the reflector opening, by a first bracket (16) which is arranged in the interior of the housing. The first bracket (16) is rotatably mounted in a second bracket (15) which for its part engages rotatably with the cubic support (2). The spherical head can be rotated about a vertical axis of rotation by 335 DEG and at the same time about a horizontal axis of rotation by 90 DEG . The two axes of rotation of the brackets are at right angles to one another. This design provides a more cost effective production of the spherical housing of the luminair and a simpler assembly thereof than before.

Title: Injection pistol for artificial insemination of cattle - has rigid main tube with leading end injection pipe extending from interior fixing
IPC: A61D19/02
Filed: 1980-03-03
Abstract: An injection pistol or syringe for artificial insemination of animals having a lone, narrow winding neck to the uterus, esp. cattle. The pistol is of the type having a main rigid tube with manually displaceable piston. The leading end of the main tube is fitted with a communicating injection pipe of semi-rigid material, e.g. polythene. The leading end of the injection pipe is bent over slightly to facilitate passage through the neck of the uterus. The joint fixing the injection pipe to the main tube is set back well inside the main tube so as not to interfere with bending the injection pipe and to improve asepsis.

Title: Frost-resistant pipe for domestic water feed - contains e.g. tube of compressible sealed cellular material which contracts when ice forms
IPC: F24D3/10
Filed: 1980-03-11
Abstract: The pipe (11) is used to convey fluid esp. water and may be incorporated in central-heating systems. It houses intermittent or continuous compressible packings (12). The volumetric relationship between the pipe and packings (12) is such that, should the water freeze, the expanding ice will compress packings with pipe damage obviated. Packings (12) have a multi-cellular closed and sealed structure containing a compressible flux e.g air. Packings may have a round cross section and may contact (12a) pipe bore to leave a crescent shaped area (13) for the water, or may have radial ribs defining an annular gap. Core cords (16) may connect packings at intervals, and alternative packings may have an annular or a spoked wheel cross-section.

Title: Electric heating control circuit - includes partial load-shedding circuit operating for timed interval if total current consumption exceeds threshold value
Inventor: ARRIBAS CECILIO
IPC: H02J3/14
Filed: 1980-05-27
Abstract: The system uses a number of radiators in different rooms of a building divided into at least two groups. A pickup provides a signal which is proportional to the total current consumed by the electric radiator network. A threshold detector connected to the pickup provides a signal when the current exceeds a certain value in order to disconnect a first group of the radiators for a timed interval. A second timing circuit then disconnects the second group of radiators for a second interval following the first. All the radiators are then reconnected and the cycle may begin again if the current threshold is still exceeded. The time intervals are of the order of a few minutes so that large temperature differences do not arise between different rooms of the building.

Title: Multicellular structure prodn. - using die for controlled injection of a gaseous blowing agent to produce closed cell foams with high levels of cell density and uniformity
IPC: B29B7/74
Filed: 1980-09-16
Abstract: Multicellular extrudates of controlled density and pore size are made by extending molten material via an annular distribution chamber (2) and a restricted convergent passage at the throat (3) of which a gaseous blowing agent is injected at a controlled pressure and frequency via a series of individual small bore passages (4) regularly spaced relative to the residual flow path to the die outlet (5).

Abstract: Composite laminated packaging material comprises (a) a strippable outer layer of LDPE; (b) a central layer of a statistical ethylene-propylene copolymer (I) and (c) an inside layer of shock-resistant polystyrene bonded to the central layer with a suitable bonding agent (II). Pref. (I) contains 2-10%, esp. 3-4% ethylene units which are sepd. from each other in the polymer chain. (II) pref. comprises ca. 50% of a sequenced butadiene-styrene elastomer with more than 50% butadiene and less than 50% styrene; ca. 50% EVA with a vinyl acetate content of more than 25%; 0.15% butylhydroxytoluene as principal antioxidant and 0.10% of the octadecyl ester of beta-(3',5'-di-tert.butyl- 4'-hydroxyphenyl) propionic acid. In use, the top LDPE layer is peeled off using suitable machinery, the lower half of the laminate is vacuum formed into containers, the containers compartments are filled with the material to be packaged, and the top layer is heat seal back onto the containers at a temp. of at least 350 deg.C and a press. of 5-25 bar bars. The laminates are esp. suitable for packaging solid and liq. dairy prods. such as butter, cheese, margarine, yoghurt, fresh cream, cottage cheese, etc. The LDPE layer can be peeled back to allow forming and filling of the containers, but forms a strong heat seal with the ethylene-propylene copolymer under the given conditions. The bonding agent maintains a good bond between the central and inner layers during the vacuum forming process.
